"Margaret Thatcher dies" joke

Margaret Thatcher dies and strolls up the pearly staircase to the pearly
gates, where she is confronted by St. Peter, brandishing a clipboard.
"Name" says St. Peter.
"Margaret Thatcher" she replies.
Peter checks through all the lists on his clipboard but cannot find the
name of our illustrious leader.
"I'm sorry" he says,"you can't come in. Your place is downstairs, in hell.
Mrs T. turns and walks down the stairs.
A short time later the phone rings. St. Peter answers it and a voice says:
"Hello Pete, It's the Devil speaking. You'll have to take that bloody woman
after all - she's only been here 10 minutes and she's closed half the
furnaces to reduce capacity"
